摘要： A mechanism for dual-height tables, counters, or the like, in which the top lifts and pivots upward and outward on pairs of links attached to the top and to link housings attached to the table or counter base. Each pair of links comprises a pivot link and a locking link. The pivot link has holes at each end which ride on pins or the like attached to a bracket on the top and the pivot link housing on the bottom. The locking link is similarly arranged at the top, with a hole for a pin attached to a bracket. The bottom end of the locking link has an elongated slot, through which a pin is inserted to fasten the locking link to the locking link housing. When the top is in the lowered position, the pin is in the end of the slot closest to the end of the locking link. As the top is raised, both links pivot on the pins in the link housings. When the top has reached its most-forward pivot position, the locking link rests on a forward stop. The locking link is then slid downward into a locking pocket in its housing, the pin moving upward in the slot until it rests on the top of the slot and the top of the table is horizontal. At this point the top is rigidly supported and locked in the forward/upward position.

摘要翻译： 一种用于双高度台，计数器等的机构，其中顶部升起并且在连接到顶部的成对链路上向上和向外枢转，并且连接到附接到桌子或反基座的壳体。 每对链节包括枢轴连杆和锁定连杆。 枢轴连杆在每一端具有孔，该孔连接在顶部上的托架上的销钉或类似物上，而在底部的枢轴连接件壳体上。 锁定链条类似地设置在顶部，具有用于连接到支架的销的孔。 锁定连杆的底端具有细长的狭槽，销插入其中以将锁定连接件紧固到锁定连接器壳体。 当顶部处于下降位置时，销处于最靠近锁定连杆端部的槽的端部。 当顶部升高时，两个连杆都可以在连杆外壳的销上枢转。 当顶部达到其最前端的枢转位置时，锁定连杆位于前进挡块上。 然后，锁定链接向下滑入其壳体中的锁定凹槽中，销在槽中向上移动，直到其搁置在槽的顶部上，并且工作台的顶部是水平的。 此时，顶部被刚性支撑并锁定在向前/向上的位置。
